Underwater gliding detector of the present utility model and other under-water robot are compared, and have volume dexterity, low cost and other advantages; Owing to do not need boosting mechanisms such as screw propeller, propelling unit, greatly reduce the power consumption of system, therefore by the power brick power supply, just can in thousands of meters depth rangees, move the several months continuously according to default course line.
Description of drawings
Fig. 1 is that the structure of underwater gliding detector becomes scheme drawing.
The specific embodiment
With reference to Fig. 1, underwater gliding detector comprises gliding type housing and variable buoyancy system, attitude control system and the communication navigation system of device in the gliding type housing:
Gliding type housing: have the gliding type shell that protection housing 1, horizontal tail 19 and empennage 10 constitute, in protection housing 1, be provided with pressure-bearing shell 26;
In order to reduce the resistance of motion of underwater gliding detector in seawater, the front and back end of protection housing is shaped as ellipse, satisfies equation:
In the formula: x, y are respectively the level and the vertical coordinate in housing elevation profile;
Variable buoyancy system: comprise outside oil sac 2, pump valve adapter plate 3, miniature electromagnetic valve 4, micropump 11, connecting rod 12, oil pocket adapter plate 13 and inner oil pocket 14, micropump 11 and miniature electromagnetic valve 4 are fixed on the pump valve adapter plate 3, inner oil pocket 14 is fixed on the oil pocket adapter plate 13, oil pocket adapter plate 13 is connected by connecting rod 12 with pump valve adapter plate 3, outside oil sac 2 is the afterbody of pressure-bearing shell 26 fixedly, between pressure-bearing shell 26 and protection housing 1;
Attitude control system: comprise header board 7, back plate 5, stepping motor 6, motor fixing frame 21, worm gear 22 that is meshed and worm screw 23, worm screw fixed mount 24, ball-screw 17, two line slideways 18, ball-screw support ring 15, line slideway support ring 16 and power brick 20, stepping motor 6 and worm screw 23 are fixing with motor fixing frame 21 that is installed in header board 7 and worm screw fixed mount 24 respectively, the rotating shaft of stepping motor 6 and worm screw 23 are coaxial fixing, worm gear 22 is connected with an end of ball-screw 17, power brick 20 is fixed on the slide block of ball-screw 17 and two line slideways 18, ball-screw 17 and two line slideways 18 are parallel to each other, power brick 20 can move forward and backward along guide rail, and the two ends of ball-screw 17 and two line slideways are installed on header board 7 and the back plate 5 by ball-screw support ring 15 and line slideway support ring 16 respectively;
Communication navigation system: comprise fixed mount 9 and the Navigation Control circuit card 8 that is installed on the fixed mount, fixed mount 9 is positioned at gliding type housing ante-chamber.Navigation Control circuit card 8 is used to realize GPS location, attitude feedback, motion control and the environmental parameters monitoring of underwater gliding detector.
Its working process is: when the underwater gliding detector rig ship for dive, miniature electromagnetic valve 4 is opened, because pressure-bearing shell 26 has been pumped into partial vacuum, the hydraulic oil in the outside oil sac 2 is pushed back in the inner oil pocket 14 under the bar pressure effect.The volume of inner oil pocket 14 begins to change, and specifies when requiring when variable quantity reaches, and miniature valve 4 is closed.Hydraulic efficiency pressure system quits work.At this moment, buoyancy is less than gravity.Underwater gliding detector begins dive.Stepping motor 6 drives the ball-screw clickwise, and power brick moves to the housing front end, and fuselage and horizontal surface form certain included angle.Specify when requiring when the fuselage leaning angle reaches, stepping motor 6 stops the rotation.Self-locking mechanism locking leading screw makes it stop operating.Underwater gliding detector slides forward with certain angle.When underwater gliding detector reached designated depth, at this moment, stepping motor 6 was started working, and drove power brick 20 and moved to the housing rear end, receded thereby make fuselage become from leaning forward.When sweptback angle reached designated value, stepping motor quit work.Then, micropump 11 is started working, and the hydraulic oil in the inner oil pocket 14 is transported to outside oil sac.When carrying oil mass to reach designated value, micropump 11 quits work.At this moment, buoyancy is greater than gravity, and underwater gliding detector begins to slide to the front upper place with certain angle.In the process of sliding, 8 pairs of marine environment of Navigation Control circuit card are monitored, and preserve monitoring result.When underwater gliding detector was about to emerge, stepping motor 6 was started working, and power brick 20 is moved to leading portion.The antenna of Navigation Control circuit card 8 is surfaced, and at this moment, the front rake of underwater gliding detector is in maxim.Aerodone begins to carry out communication with satellite.After communication finished, underwater gliding detector entered working cycle next time.
